<div><h2 id="description">Description</h2>
<div class="description"><div class="ng-http-page"><p>The <code>$http</code> service is a core Angular service that facilitates communication with the remote
HTTP servers via the browser&#39;s <a href="https://developer.mozilla.org/en/xmlhttprequest">XMLHttpRequest</a> object or via <a href="http://en.wikipedia.org/wiki/JSONP">JSONP</a>.</p>
<p>For unit testing applications that use <code>$http</code> service, see
<a href="api/ngMock.$httpBackend">$httpBackend mock</a>.</p>
<p>For a higher level of abstraction, please check out the <a href="api/ngResource.$resource">$resource</a> service.</p>
<p>The $http API is based on the <a href="api/ng.$q"><code>deferred/promise APIs</code></a> exposed by
the $q service. While for simple usage patterns this doesn&#39;t matter much, for advanced usage
it is important to familiarize yourself with these APIs and the guarantees they provide.</p>
<h3 id="description_general-usage">General usage</h3>
<p>The <code>$http</code> service is a function which takes a single argument — a configuration object —
that is used to generate an HTTP request and returns  a <a href="api/ng.$q"><code>promise</code></a>
with two $http specific methods: <code>success</code> and <code>error</code>.</p>
<pre class="prettyprint linenums">
  $http({method: 'GET', url: '/someUrl'}).
    success(function(data, status, headers, config) {
      // this callback will be called asynchronously
      // when the response is available
    }).
    error(function(data, status, headers, config) {
      // called asynchronously if an error occurs
      // or server returns response with an error status.
    });
</pre>
<p>Since the returned value of calling the $http function is a <code>promise</code>, you can also use
the <code>then</code> method to register callbacks, and these callbacks will receive a single argument –
an object representing the response. See the API signature and type info below for more
details.</p>
<p>A response status code between 200 and 299 is considered a success status and
will result in the success callback being called. Note that if the response is a redirect,
XMLHttpRequest will transparently follow it, meaning that the error callback will not be
called for such responses.</p>
<h3 id="description_calling-$http-from-outside-angularjs">Calling $http from outside AngularJS</h3>
<p>The <code>$http</code> service will not actually send the request until the next <code>$digest()</code> is
executed. Normally this is not an issue, since almost all the time your call to <code>$http</code> will
be from within a <code>$apply()</code> block.
If you are calling <code>$http</code> from outside Angular, then you should wrap it in a call to
<code>$apply</code> to cause a $digest to occur and also to handle errors in the block correctly.</p>
<pre><code>$scope.$apply(function() {
  $http(...);
});</code></pre>
<h3 id="description_writing-unit-tests-that-use-$http">Writing Unit Tests that use $http</h3>
<p>When unit testing you are mostly responsible for scheduling the <code>$digest</code> cycle. If you do
not trigger a <code>$digest</code> before calling <code>$httpBackend.flush()</code> then the request will not have
been made and <code>$httpBackend.expect(...)</code> expectations will fail.  The solution is to run the
code that calls the <code>$http()</code> method inside a $apply block as explained in the previous
section.</p>
<pre><code>$httpBackend.expectGET(...);
$scope.$apply(function() {
  $http.get(...);
});
$httpBackend.flush();</code></pre>
<h3 id="description_shortcut-methods">Shortcut methods</h3>
<p>Since all invocations of the $http service require passing in an HTTP method and URL, and
POST/PUT requests require request data to be provided as well, shortcut methods
were created:</p>
<pre class="prettyprint linenums">
  $http.get('/someUrl').success(successCallback);
  $http.post('/someUrl', data).success(successCallback);
</pre>
<p>Complete list of shortcut methods:</p>
<ul>
<li><a href="api/ng.$http#methods_get"><code>$http.get</code></a></li>
<li><a href="api/ng.$http#methods_head"><code>$http.head</code></a></li>
<li><a href="api/ng.$http#methods_post"><code>$http.post</code></a></li>
<li><a href="api/ng.$http#methods_put"><code>$http.put</code></a></li>
<li><a href="api/ng.$http#methods_delete"><code>$http.delete</code></a></li>
<li><a href="api/ng.$http#methods_jsonp"><code>$http.jsonp</code></a></li>
</ul>
<h3 id="description_setting-http-headers">Setting HTTP Headers</h3>
<p>The $http service will automatically add certain HTTP headers to all requests. These defaults
can be fully configured by accessing the <code>$httpProvider.defaults.headers</code> configuration
object, which currently contains this default configuration:</p>
<ul>
<li><code>$httpProvider.defaults.headers.common</code> (headers that are common for all requests):<ul>
<li><code>Accept: application/json, text/plain, * / *</code></li>
</ul>
</li>
<li><code>$httpProvider.defaults.headers.post</code>: (header defaults for POST requests)<ul>
<li><code>Content-Type: application/json</code></li>
</ul>
</li>
<li><code>$httpProvider.defaults.headers.put</code> (header defaults for PUT requests)<ul>
<li><code>Content-Type: application/json</code></li>
</ul>
</li>
</ul>
<p>To add or overwrite these defaults, simply add or remove a property from these configuration
objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
with the lowercased HTTP method name as the key, e.g.
`$httpProvider.defaults.headers.get = { &#39;My-Header&#39; : &#39;value&#39; }.</p>
<p>The defaults can also be set at runtime via the <code>$http.defaults</code> object in the same
fashion. In addition, you can supply a <code>headers</code> property in the config object passed when
calling <code>$http(config)</code>, which overrides the defaults without changing them globally.</p>
<h3 id="description_transforming-requests-and-responses">Transforming Requests and Responses</h3>
<p>Both requests and responses can be transformed using transform functions. By default, Angular
applies these transformations:</p>
<p>Request transformations:</p>
<ul>
<li>If the <code>data</code> property of the request configuration object contains an object, serialize it
into JSON format.</li>
</ul>
<p>Response transformations:</p>
<ul>
<li>If XSRF prefix is detected, strip it (see Security Considerations section below).</li>
<li>If JSON response is detected, deserialize it using a JSON parser.</li>
</ul>
<p>To globally augment or override the default transforms, modify the
<code>$httpProvider.defaults.transformRequest</code> and <code>$httpProvider.defaults.transformResponse</code>
properties. These properties are by default an array of transform functions, which allows you
to <code>push</code> or <code>unshift</code> a new transformation function into the transformation chain. You can
also decide to completely override any default transformations by assigning your
transformation functions to these properties directly without the array wrapper.</p>
<p>Similarly, to locally override the request/response transforms, augment the
<code>transformRequest</code> and/or <code>transformResponse</code> properties of the configuration object passed
into <code>$http</code>.</p>
<h3 id="description_caching">Caching</h3>
<p>To enable caching, set the request configuration <code>cache</code> property to <code>true</code> (to use default
cache) or to a custom cache object (built with <a href="api/ng.$cacheFactory"><code><code>$cacheFactory</code></code></a>).
When the cache is enabled, <code>$http</code> stores the response from the server in the specified
cache. The next time the same request is made, the response is served from the cache without
sending a request to the server.</p>
<p>Note that even if the response is served from cache, delivery of the data is asynchronous in
the same way that real requests are.</p>
<p>If there are multiple GET requests for the same URL that should be cached using the same
cache, but the cache is not populated yet, only one request to the server will be made and
the remaining requests will be fulfilled using the response from the first request.</p>
<p>You can change the default cache to a new object (built with
<a href="api/ng.$cacheFactory"><code><code>$cacheFactory</code></code></a>) by updating the
<a href="api/ng.$http#properties_defaults"><code><code>$http.defaults.cache</code></code></a> property. All requests who set
their <code>cache</code> property to <code>true</code> will now use this cache object.</p>
<p>If you set the default cache to <code>false</code> then only requests that specify their own custom
cache object will be cached.</p>
<h3 id="description_interceptors">Interceptors</h3>
<p>Before you start creating interceptors, be sure to understand the
<a href="api/ng.$q"><code>$q and deferred/promise APIs</code></a>.</p>
<p>For purposes of global error handling, authentication, or any kind of synchronous or
asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
able to intercept requests before they are handed to the server and
responses before they are handed over to the application code that
initiated these requests. The interceptors leverage the <a href="api/ng.$q"><code>promise APIs</code></a> to fulfill this need for both synchronous and asynchronous pre-processing.</p>
<p>The interceptors are service factories that are registered with the <code>$httpProvider</code> by
adding them to the <code>$httpProvider.interceptors</code> array. The factory is called and
injected with dependencies (if specified) and returns the interceptor.</p>
<p>There are two kinds of interceptors (and two kinds of rejection interceptors):</p>
<ul>
<li><code>request</code>: interceptors get called with http <code>config</code> object. The function is free to
modify the <code>config</code> or create a new one. The function needs to return the <code>config</code>
directly or as a promise.</li>
<li><code>requestError</code>: interceptor gets called when a previous interceptor threw an error or
resolved with a rejection.</li>
<li><code>response</code>: interceptors get called with http <code>response</code> object. The function is free to
modify the <code>response</code> or create a new one. The function needs to return the <code>response</code>
directly or as a promise.</li>
<li><code>responseError</code>: interceptor gets called when a previous interceptor threw an error or
resolved with a rejection.</li>
</ul>
<pre class="prettyprint linenums">
  // register the interceptor as a service
  $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
    return {
      // optional method
      'request': function(config) {
        // do something on success
        return config || $q.when(config);
      },

      // optional method
     'requestError': function(rejection) {
        // do something on error
        if (canRecover(rejection)) {
          return responseOrNewPromise
        }
        return $q.reject(rejection);
      },



      // optional method
      'response': function(response) {
        // do something on success
        return response || $q.when(response);
      },

      // optional method
     'responseError': function(rejection) {
        // do something on error
        if (canRecover(rejection)) {
          return responseOrNewPromise
        }
        return $q.reject(rejection);
      };
    }
  });

  $httpProvider.interceptors.push('myHttpInterceptor');


  // register the interceptor via an anonymous factory
  $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
    return {
     'request': function(config) {
         // same as above
      },
      'response': function(response) {
         // same as above
      }
    };
  });

<h3 id="description_response-interceptors">Response interceptors (DEPRECATED)</h3>
<p>Before you start creating interceptors, be sure to understand the
<a href="api/ng.$q"><code>$q and deferred/promise APIs</code></a>.</p>
<p>For purposes of global error handling, authentication or any kind of synchronous or
asynchronous preprocessing of received responses, it is desirable to be able to intercept
responses for http requests before they are handed over to the application code that
initiated these requests. The response interceptors leverage the <a href="api/ng.$q"><code>promise apis</code></a> to fulfil this need for both synchronous and asynchronous preprocessing.</p>
<p>The interceptors are service factories that are registered with the $httpProvider by
adding them to the <code>$httpProvider.responseInterceptors</code> array. The factory is called and
injected with dependencies (if specified) and returns the interceptor  — a function that
takes a <a href="api/ng.$q"><code>promise</code></a> and returns the original or a new promise.</p>
<pre class="prettyprint linenums">
  // register the interceptor as a service
  $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
    return function(promise) {
      return promise.then(function(response) {

        return response;
      }, function(response) {
        // do something on error
        if (canRecover(response)) {
          return responseOrNewPromise
        }
        return $q.reject(response);
      });
    }
  });

  $httpProvider.responseInterceptors.push('myHttpInterceptor');


  // register the interceptor via an anonymous factory
  $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) {
    return function(promise) {
      // same as above
    }
  });

<h3 id="description_security-considerations">Security Considerations</h3>
<p>When designing web applications, consider security threats from:</p>
<ul>
<li><a href="http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx">JSON vulnerability</a></li>
<li><a href="http://en.wikipedia.org/wiki/Cross-site_request_forgery">XSRF</a></li>
</ul>
<p>Both server and the client must cooperate in order to eliminate these threats. Angular comes
pre-configured with strategies that address these issues, but for this to work backend server
cooperation is required.</p>
<h4 id="description_security-considerations_json-vulnerability-protection">JSON Vulnerability Protection</h4>
<p>A <a href="http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx">JSON vulnerability</a> allows third party website to turn your JSON resource URL into
<a href="http://en.wikipedia.org/wiki/JSONP">JSONP</a> request under some conditions. To
counter this your server can prefix all JSON requests with following string <code>&quot;)]}&#39;,\n&quot;</code>.
Angular will automatically strip the prefix before processing it as JSON.</p>
<p>For example if your server needs to return:
<pre class="prettyprint linenums">
['one','two']
</pre>
<p>which is vulnerable to attack, your server can return:
<pre class="prettyprint linenums">
)]}',
['one','two']
</pre>
<p>Angular will strip the prefix, before processing the JSON.</p>
<h4 id="description_security-considerations_cross-site-request-forgery-protection">Cross Site Request Forgery (XSRF) Protection</h4>
<p><a href="http://en.wikipedia.org/wiki/Cross-site_request_forgery">XSRF</a> is a technique by which
an unauthorized site can gain your user&#39;s private data. Angular provides a mechanism
to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
(by default, <code>XSRF-TOKEN</code>) and sets it as an HTTP header (<code>X-XSRF-TOKEN</code>). Since only
JavaScript that runs on your domain could read the cookie, your server can be assured that
the XHR came from JavaScript running on your domain. The header will not be set for
cross-domain requests.</p>
<p>To take advantage of this, your server needs to set a token in a JavaScript readable session
cookie called <code>XSRF-TOKEN</code> on the first HTTP GET request. On subsequent XHR requests the
server can verify that the cookie matches <code>X-XSRF-TOKEN</code> HTTP header, and therefore be sure
that only JavaScript running on your domain could have sent the request. The token must be
unique for each user and must be verifiable by the server (to prevent the JavaScript from
making up its own tokens). We recommend that the token is a digest of your site&#39;s
authentication cookie with a <a href="https://en.wikipedia.org/wiki/Salt_(cryptography)">salt</a>
for added security.</p>
<p>The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
properties of either $httpProvider.defaults, or the per-request config object.</p>
